Kowa LMZ250AM 1/2" 10-250mm Zoom Auto Iris Lens (Video)

Quick Overview

1/2", 10-250mm, Auto Iris.

Common in lenses in the broadcast industry, the 3-Cam Design is also incorporated in Kowa’s varifocal and zoom lenses. This innovative system has solved the problem of de-centering which sometimes occurs in the conventional pole system. Not only is the movement of the lens impaired by de-centering, but the optical performance suffers too. The 3-Cam Design also reduces internal reflection. As a result, the image obtained by this design is much sharper than that of the conventional pole system. With the 3-Cam Design, the customer can expect higher optical performance and a longer service life.


  • Outstanding Light Gathering Ability - The LMZ250AM series has a maximum aperture of 1:1.5. The combination of this large focal range and quick aperture rating guarantees a distinguished optical performance
  • Powerful 25x Zoom Ratio - This lens is suitable for monitoring a variety of applications including surveillance of highway traffic and remote monitoring of port/bay areas, borders and stadiums
  • Excellent Durability - The LMZ250AM provides high resolution pictures without de-centering by means of the smooth 3-CAM system. This system provides long service life of the motor and it's structure by minimizing resistance
